Agnes Belgradin is in love with a young doctor, Loring Brent. When Agnes' father dies, her mother takes her on a trip abroad. She insists that the young couple separate before they set sail, and promises that if they still love each other after a year they can reunite. But Mrs. Belgradin intercepts all the letters Agnes and Brent write one another, and convinces her daughter to marry a wealthy Australian millionaire.
